Given numbers are 725, 540, 947, 644

The list of prime factors of all numbers are

Prime factors of 725 are 5 x 5 x 29

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 947 are 947

Prime factors of 644 are 2 x 2 x 7 x 23

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 725, 540, 947, 644

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(725, 540) = 78300

GCD(725, 540) = ( 725 x 540 ) / 78300

= 725 / 540

= 725

Step2:

LCM(5, 947) = 4735

GCD(5, 947) = ( 5 x 947 ) / 4735

= 5 / 947

= 5

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 725, 540, 947, 644 is 1
